I can't seem to get UART to work on Radxa Zero 3W System info https://paste.next.armbian.com/savaleceqe The usual enable UART options (that I see with other boards) do not show up under armbian-config->System->Kernel->Manage Device Tree Overlays. (In fact very little shows up there, all the usual SPI / i2c / w1 / usbhost etc are all missing). I did decompile /boot/dtb/rockchip/rk3566-radxa-zero3.dtb to take a look at what in their, and UART1,2,3,4,5,6,7 along with other missing options armbian-config are their, but the references to other files look to be missing IF (and that's a big IF) I am understanding the dtb / dts correctly. Within /boot/dtb/rockchip/rk3566-radxa-zero3.dtb with the symbols stanza I see the following __symbols__ { uart1 = "/serial@fe650000"; uart2 = "/serial@fe660000"; uart3 = "/serial@fe670000"; } I'm assuming uart1 is referancing this section within the same file serial@fe650000 { compatible = "rockchip,rk3568-uart\0snps,dw-apb-uart"; reg = <0x00 0xfe650000 0x00 0x100>; interrupts = <0x00 0x75 0x04>; clocks = <0x24 0x11f 0x24 0x11c>; clock-names = "baudclk\0apb_pclk"; dmas = <0x44 0x02 0x44 0x03>; pinctrl-0 = <0xe7 0xe8>; pinctrl-names = "default"; reg-io-width = <0x04>; reg-shift = <0x02>; status = "okay"; phandle = <0x1a1>; }; What I can't find are any file named rk3568-uart on my system, but I can find files like rk3576-uart* Same goes for all the other missing items like i2c, spi, etc. I have no idea if this is the reason. But would love some help on this as I don;t want to move to a different distribution. Thanks.
